Patented Feb. 24, 1931 UNITED STAT-Es kPATENT orifice HARRY LiivY ANDSAMUEL LoNscHEiN, or NEW YORK, N.l Y.; sain LEVY AssiGNon y To SAIDLoNscHniN ik POCKET' IMPRESSION SEAL Application filed December 9, 1929.Serial No. 412,664.

This invention relates to newzand useful improvements.infseals.

Existing seals such as used by iiotaiies and othersfare operated bypivoted levers at right H angles to the planes oi the impression blocksthereof.v Necessarily the shape of the device is quite-bulky andawkward.V This prevents the'carrying of such a device in ones pocket.unless he is willing to stand for much inconl'venience.

It isfproposed to construct a pocket. seal Awith' an operating handleconnected with a helixpressure stud, and moving in a plane parallelvwith .the plane of the Iimpression Thus when the device is ina foldedposition, the parts are flat andinay be conveniently carried in onespocket without excessive bulk. In addition, the helix arrangement givesa great mechanical advantage even though' it occupies a very smallspace.

i More particularly,`the invention proposes a Ushaped body having armsJoined at one of their ends, animpression block .mounted 'on the innerside of one of the arms and engageable -by a complementary impressionvblock movablymounted between the arms and urgeable into engagement by ahelix pressure stud mounted .thruY the other of the arms and operable bya handle movablein ai plane parallel to the planes of the impressionblocks. x

Forfurther comprehension of the invenrtion, and'of the .objects-andadvant'agesthere-v of, reference will be had to'tlie following de-'scription'and 'accompanying drawings, -and tothe appended claims inwhich the various novel. features of the invention'are moreparticularlyset forth. l

Fig. 7 is an enlarged longitudinal vertical sectional view taken on theline 7 7 of Fig. 1.

Fig. 8 is a perspective View of a handle similar to the one illustratedin Fig. 1 but of inodied form.

The device consists of a U shaped body having an arm 10 and a second arm11 joined to each other at one of their ends. An impression block 12 ismounted upon the inner side of the arm 11 and is engageable by acomplementary impression block 13 movably arranged between the arms andurgeable into engagement by a helix `pressure stud 14 mounted thru theother of the arms and operable by a handle 15. f

The said arms 10 and 11 at their joined ends are held together by alarge screw 16, and have interengaging lips 17 and 18 for relieving someof the strain from the screw during use Yof the device. Furthermore, thelips prevent relative rotating of the two arms even though only clampedby one screw.

The said arm 11 is formed with a recess 19 in which the said impressionblock 12 rests. This recess necessarily is located on the inner side ofthe arm, and an aperture 20 in the arm communicates therewith sol thatthe impression block may bevlrnocked .out from the recess if this isdesired. The pitch oi' the helix stud 14 is quite large so that uponmovement of approximately it will have f advanced sufficiently to causeengagement et the impression blocks.

A. leaf spring. 21is disposed between the arms 10 and 11, and at one ofits ends is engaged between the joined.. ends of the arms. A pair ofscrews 22 serve to fasten the leal spring uponr the'arni 11. Thesaidcompleinentary impression block 13 is attachedupon the leaf spring 21and this constitutes the movable mounting thereof.

A stoppin 23 projectsfrcmthe top iaccor :the arm 10 near one edgethereof and serves as a stop for the handle 15.A In the 'closed positionof thehandle, it is only possible toA iiioveit to its open positionsincerit is limited againstjrotation inthe wrong diree tion by the pin.A snap catch Q4 is arranged for holding the handle in its closedposition and consists of a' ball 25 pressed outwards by a spring 26mounted in the arm l0. Thel handle l5 is formed with a'smail recess intowhich the lball engages-aud accomplishes the latching. This maybe lseenfrom an inspection of Fig. y a

Preferably the device should be constructed pear-shaped in planviewIfor'convenience `in handling and for small constructionfThe handle l5 isformed with an opening?? constituting a linger opening forthemanipulation thereof. Attention is called to .in which the handle isshown in its closed position and the impression blocks-together. Fig. 7the handle` is shown in itsopenposi- `tion* and :the impressionbloclrs'separated.

Aln Fig.. 8a modified form of handle has been-.illustrated for thedevice. At .times when the sealis usedupon fairlyteugh paper, it may henecessary to increasefitheieverage and this isaccompl-shed`byf,theadjustable handle. The .handle indicated by reference numeral l5consists of: two sectionsslidably connected 'preferably by.a.rdovetailedconstruction and,` limited ,against complete .dis-

i engagement by arpin Q8 projecting from one of the sections andengaging in a slot 29 in the other-section. .The slidable' connectionshould be :quite tight so lthat friction cani be depended upon tomaintain the .handle in its contracted fposition. -For increasing theleverage it is only necessary .tn draw the sec; tionsapart. f Access maybe had to the impression blocks for purposesof repairorreplacement by`re- .moving the screw. 1G. Then the arms ldand :llanay b e'separated.Upon a'. removing of the screws 22, the leaf spring 21 may-'bedisengagedand the* .nnpressionblocks are exposed.
